We will want to use the Pythagorean theorem
a^2 + b^2 = c^2
We can plug in the values we know
7^2 + 9^2 = c^2
49 + 81 = c^2
130 = c^2
We will then square both sides to get c by itself
c = 11.4 meters

Answer:

I'll setup the problem and leave the computation to you

Step-by-step explanation:

The equation to calculate fixed payments

$P = \frac{r(PV)}{1- {(1 + r)}^{ - n} }$

P= payments

r = interest rate for the period (which is a quarter )

PV = present value (or the amount borrowed)

n = number of periods

r = .25/4 (4 months = quarter of a year)

n = 4*10

PV = R450550.00
